WS/XSUL Web Services Toolkit
WS/XSUL v2 (a.k.a. XSOAP4) is a very modular Java library to construct web services that uses XML with a strong support for XML Schemas and WSDL 1.1 doc/literal bindings.
I have never heard of Alexander Slominski’s XSUL before; this definitely merits a closer look.
yet another wrapper for XMLBeans, AIUI, but at least they trumpet WSDL first..
